Selective Mutism Indian Medical PG Practice Questions and MCQs
Question 1: Which of the following disorders is classified under somatic symptom and related disorders in the DSM-5?
- A. Post-Traumatic Stress Disorder (PTSD)
- B. Phobic disorders (e.g., social anxiety disorder)
- C. Conversion disorder (functional neurological symptom disorder) (Correct Answer)
- D. Obsessive-Compulsive Disorder (OCD)
Explanation: ***Conversion disorder (functional neurological symptom disorder)*** - **Conversion disorder** is characterized by neurological symptoms (e.g., paralysis, blindness) that are **incompatible with recognized neurological or medical conditions**, yet are not intentionally produced. - It falls under **somatic symptom and related disorders** because the primary features are physical symptoms causing distress or functional impairment, rather than being malingered or feigned. *Phobic disorders (e.g., social anxiety disorder)* - **Phobic disorders** are classified under **anxiety disorders** in the DSM-5, not somatic symptom and related disorders. - They are primarily characterized by **intense, irrational fears** of specific objects or situations, leading to avoidance rather than prominent physical symptoms without a medical cause. *Post-Traumatic Stress Disorder (PTSD)* - **PTSD** is classified under **trauma- and stressor-related disorders** in the DSM-5, distinguished by symptoms developing after exposure to a traumatic event. - Its core features include **intrusive memories, avoidance, negative alterations in cognition and mood, and alterations in arousal and reactivity**, rather than unexplained physical symptoms. *Obsessive-Compulsive Disorder (OCD)* - **OCD** is classified under **obsessive-compulsive and related disorders** in the DSM-5. - It is primarily characterized by the presence of **obsessions (recurrent, intrusive thoughts)** and/or **compulsions (repetitive behaviors or mental acts)**, which are distinct from somatic symptoms.
Question 2: Which of the following is a CORE diagnostic criterion of autistic spectrum disorder according to DSM-5?
- A. Impaired communication (Correct Answer)
- B. Impaired imagination
- C. Language developmental delay
- D. Vision problems
Explanation: ***Impaired communication*** - Deficits in **social communication and social interaction** are one of the two core diagnostic criteria for Autism Spectrum Disorder (ASD) in DSM-5. - This includes deficits in social-emotional reciprocity, nonverbal communicative behaviors, and developing/maintaining relationships. - Communication impairments are essential for diagnosis and must be present across multiple contexts. *Impaired imagination* - While restricted, repetitive patterns of behavior (which can include rigid thinking patterns) are the second core criterion, "impaired imagination" is not specifically listed as a core diagnostic criterion in DSM-5. - Imaginative play deficits may be present but fall under the broader category of restricted/repetitive behaviors, not as a standalone core criterion. *Language developmental delay* - Language delay is **not a core diagnostic criterion** in DSM-5 for ASD. - DSM-5 explicitly states that ASD can occur with or without accompanying language impairment. - When present, language delay is noted as a specifier, not a required criterion. *Vision problems* - Vision problems are not a characteristic feature of Autism Spectrum Disorder. - Any vision issues in individuals with ASD are co-occurring conditions unrelated to the core diagnostic features.
Question 3: A 2.5 year old boy is brought by the parents because of the concern that he is not developing appropriately. Child often is unable to engage with others using eye contact and does not play with other children. He continuously bangs his head against the wall and remains confined to himself most of the time. What is the most likely diagnosis?
- A. Conduct disorder
- B. Social phobia
- C. Autism (Correct Answer)
- D. ADHD
Explanation: ***Autism*** - The child's lack of **eye contact**, inability to **play with other children**, and repetitive self-stimulatory behavior (banging head) are classic signs of **autism spectrum disorder (ASD)**. - ASD is characterized by persistent deficits in **social communication** and **social interaction** across multiple contexts, along with restricted, repetitive patterns of behavior, interests, or activities. *Conduct disorder* - Characterized by a repetitive and persistent pattern of behavior in which the **basic rights of others** or major age-appropriate **societal norms or rules are violated**. - Symptoms include aggression to people and animals, destruction of property, deceitfulness or theft, and serious violations of rules, which are not described in this case. *Social phobia* - Involves an intense, persistent fear of social or performance situations where the individual fears **embarrassment** or **humiliation**. - While there is social avoidance, it is driven by fear of negative evaluation rather than a fundamental inability to engage socially or repetitive behaviors. *ADHD* - Primarily defined by persistent patterns of **inattention** and/or **hyperactivity-impulsivity** that interfere with functioning or development. - While children with ADHD may have social difficulties, the core symptoms of lack of eye contact, repetitive behaviors, and profound social engagement deficits are not typical of ADHD.
Question 4: Which of the following treatments cannot be used for management of Obsessive Compulsive Disorder (OCD)?
- A. Fluoxetine
- B. Carbamazepine (Correct Answer)
- C. Cognitive Behaviour Therapy
- D. Clomipramine
Explanation: ***Carbamazepine*** - **Carbamazepine** is an **anticonvulsant** and **mood stabilizer** primarily used for epilepsy and bipolar disorder. - It does not have established efficacy for the treatment of **Obsessive-Compulsive Disorder (OCD)**. *Fluoxetine* - **Fluoxetine** is a **Selective Serotonin Reuptake Inhibitor (SSRI)** and is a **first-line pharmacotherapy** for OCD. - SSRIs, including fluoxetine, are effective in reducing the severity of **obsessions and compulsions**. *Cognitive Behaviour Therapy* - **Cognitive Behavioural Therapy (CBT)**, specifically **Exposure and Response Prevention (ERP)**, is the **gold standard psychotherapy** for OCD. - It involves gradually exposing patients to feared situations or thoughts while preventing their ritualistic responses. *Clomipramine* - **Clomipramine** is a **tricyclic antidepressant (TCA)** that has potent inhibitory effects on **serotonin reuptake**. - It is one of the **most effective medications** for OCD, often used when SSRIs are insufficient.
Question 5: Best therapy suited to teach daily life skill to a mentally challenged child:
- A. Contingency management (Correct Answer)
- B. Cognitive reconstruction
- C. Self instruction
- D. CBT (Cognitive behavior therapy)
Explanation: ***Contingency management*** - This therapy involves consistently **rewarding desired behaviors** and withholding rewards for undesirable ones, which is highly effective for teaching new skills to individuals with intellectual disabilities. - It uses principles of **operant conditioning** to shape behavior through positive reinforcement, making it suitable for acquiring daily living skills. *Cognitive reconstruction* - This technique focuses on identifying and changing **maladaptive thought patterns**, which typically requires a higher level of cognitive function. - It is generally not the primary or most effective approach for teaching concrete daily life skills to individuals with significant **cognitive limitations**. *Self instruction* - This involves teaching individuals to guide their own behavior using **internal verbal cues** or self-talk. - While beneficial for some, it often requires a certain degree of **abstract thinking** and memory, making it less suitable as a standalone method for those with profound cognitive challenges in acquiring basic skills. *CBT (Cognitive behavior therapy)* - CBT integrates cognitive and behavioral strategies to address emotional and behavioral problems by modifying **thoughts, feelings, and behaviors**. - While beneficial for a range of psychological issues, its emphasis on **cognitive restructuring** makes it less directly applicable or the most effective first-line therapy for teaching concrete, functional daily living skills to mentally challenged children.
Question 6: A first-grade teacher is concerned about a 6-year-old girl in her class who has not spoken a single word since school started. The little girl participates appropriately in the class activities and uses gestures, drawings, nods, and shakes her head to communicate. The parents report that the little girl talks only at home and only in the presence of her closest relatives. Which of the following is the most appropriate diagnosis?
- A. Autism
- B. Selective mutism (Correct Answer)
- C. Expressive language disorder
- D. School phobia
Explanation: ***Selective mutism*** - This condition is characterized by a **consistent failure to speak in specific social situations** (e.g., school) despite speaking in other situations (e.g., at home with close family). - The child's **appropriate participation in class activities** and use of alternative communication methods (gestures, drawings) are typical features. *Autism* - Children with autism spectrum disorder often exhibit **deficits in social-emotional reciprocity** and may have **restricted, repetitive patterns of behavior or interests**. - While they may have communication challenges, the selective nature of the mutism and otherwise appropriate social engagement in the classroom argue against autism. *Expressive language disorder* - This disorder involves difficulty **producing spoken language**, regardless of the setting. - The fact that the child speaks normally at home suggests her expressive language abilities are intact, making this diagnosis unlikely. *School phobia* - School phobia, now often referred to as **school refusal**, is characterized by symptoms of anxiety or panic when attending or anticipating school. - While the child might be anxious, her ability to participate in class activities and communicate nonverbally suggests the primary issue is not an avoidance of school itself but a selective inability to speak.
Question 7: A 15-year-old adolescent is brought in for evaluation due to repeated failure to conform to social norms, deceitfulness, impulsivity, and lack of remorse. What is the most likely diagnosis?
- A. Conduct disorder (Correct Answer)
- B. Oppositional defiant disorder
- C. Intermittent explosive disorder
- D. Antisocial personality disorder
Explanation: ***Conduct disorder*** - This diagnosis is characterized by repeated patterns of behavior that **violate the rights of others** or major societal norms, consistent with the patient's presentation of **deceitfulness, impulsivity, and lack of remorse**. - For individuals under 18, it is the appropriate diagnosis, as **Antisocial Personality Disorder** cannot be diagnosed before turning 18. *Oppositional defiant disorder* - This condition involves a pattern of **angry/irritable mood, argumentative/defiant behavior**, or vindictiveness. It does not typically include the severe violations of societal norms or the rights of others seen in this case. - While there is defiance, it generally lacks the **aggression** towards people/animals, **destruction of property**, or **deceitfulness/theft** that characterize conduct disorder. *Intermittent explosive disorder* - This disorder is marked by **recurrent behavioral outbursts** representing a failure to control aggressive impulses. - The outbursts are typically **disproportionate** to the provocation but do not necessarily involve the persistent pattern of violating others' rights or societal rules as described. *Antisocial personality disorder* - This diagnosis requires an individual to be at least **18 years old** and have a history of conduct disorder symptoms before age 15. - Although the symptoms align with the criteria for **antisocial behavior**, the patient's age (15 years old) precludes this diagnosis.
Question 8: A four year old boy Tinu has normal developmental milestones except delayed speech. He is interested to watch spinning objects like fan and the washing machine. His parents struggle to get him interested in other children at home. People often comment that he is disinterested and self centred. What will be your thought regarding his diagnosis?
- A. Specific learning disability
- B. Intellectual disability
- C. Sibling Rivalry
- D. Autism Spectrum Disorder (Correct Answer)
Explanation: ***Autism Spectrum Disorder*** - The child's delayed speech, **restricted interests** (spinning objects), lack of social engagement, and difficulty interacting with other children are classic symptoms of **Autism Spectrum Disorder (ASD)**. - Normal developmental milestones in other areas, such as motor skills, differentiate ASD from global developmental delays. - The **triad of impairments** includes social communication deficits, restricted interests, and repetitive behaviors, all evident in this case. *Specific learning disability* - This diagnosis typically presents with difficulties in specific academic areas like reading, writing, or math in a child with otherwise average intelligence. - It is generally diagnosed after school entry (age 6-7 years) when academic demands increase. - It doesn't explain the **social communication deficits** and **restricted, repetitive behaviors** seen in this case. *Intellectual disability* - This condition involves significant limitations in both intellectual functioning and adaptive behavior, with onset during the developmental period. - While delayed speech can be a feature, the child's otherwise **normal developmental milestones** in motor and other domains argue against a global intellectual deficit. - The **restricted interests** and social deficits are more characteristic of ASD than intellectual disability alone. *Sibling Rivalry* - This refers to competition or animosity between siblings, often manifesting as behavioral problems or attention-seeking from parents. - It is a normal developmental phenomenon, not a psychiatric disorder. - It does not account for the core symptoms described, such as **delayed speech**, **restricted interests** (fascination with spinning objects), or a pervasive disinterest in social interaction.
Question 9: Which of the following is not a central characteristic of childhood autism?
- A. Callous and unemotional traits (Correct Answer)
- B. Impaired communication
- C. Restricted, repetitive behaviour
- D. Impaired social interaction
Explanation: ***Callous and unemotional traits*** - While some individuals with autism may struggle with empathy, **callous and unemotional traits** are not a core diagnostic feature of autism spectrum disorder (ASD); they are more commonly associated with conditions like **conduct disorder** or **antisocial personality disorder**. - **Emotional dysregulation** and **difficulty recognizing others' emotions** are common in autism, but this differs from a pervasive pattern of callousness. *Impaired communication* - **Impaired verbal and nonverbal communication** is a fundamental diagnostic criterion for autism spectrum disorder, ranging from absent speech to difficulties with conversations and understanding social cues. - This can manifest as problems with **initiating or maintaining conversations**, **lack of eye contact**, and **unusual tone of voice**. *Restricted, repetitive behaviour* - **Restricted, repetitive patterns of behavior, interests, or activities** are a core diagnostic feature of ASD. - Examples include **stereotyped motor movements**, **insistence on sameness**, **highly restricted or fixated interests**, and **unusual sensory sensitivities**. *Impaired social interaction* - **Persistent deficits in social communication and social interaction** across multiple contexts are defining characteristics of autism. - This includes difficulties with **social-emotional reciprocity**, **nonverbal communication**, and **developing, maintaining, and understanding relationships**.
Question 10: Along with a pleasant stimulus, noxious stimuli are given in the treatment of alcohol dependence or sexual disorder. This is which of the following types of behavior therapy?
- A. Negative reinforcement
- B. Aversion therapy (Correct Answer)
- C. Punishment
- D. Flooding
Explanation: ### Explanation **Correct Answer: B. Aversion Therapy** **Aversion therapy** is a form of behavior therapy based on the principle of **Classical Conditioning**. It involves the repeated pairing of an undesirable but pleasant stimulus (e.g., alcohol or paraphilic triggers) with an unpleasant/noxious stimulus (e.g., electric shocks, emetics like disulfiram, or unpleasant odors). Over time, the patient develops a conditioned aversion to the previously pleasurable stimulus, leading to a reduction in the unwanted behavior. It is commonly used in treating alcohol dependence, smoking, and certain sexual disorders. **Why other options are incorrect:** * **A. Negative Reinforcement:** This involves the **removal** of an unpleasant stimulus to increase the frequency of a desired behavior (e.g., taking an aspirin to remove a headache). In the question, a noxious stimulus is *added*, not removed. * **C. Punishment:** While similar, punishment is an **Operant Conditioning** concept where a consequence follows a behavior to decrease its frequency. Aversion therapy is specifically the *pairing* of stimuli to change the emotional response (Classical Conditioning). * **D. Flooding:** This is a technique used for phobias and OCD where the patient is directly exposed to their maximum feared stimulus (prolonged exposure) until the anxiety response extinguishes. It does not involve noxious stimuli like shocks or chemicals. **High-Yield Clinical Pearls for NEET-PG:** * **Disulfiram (Antabuse):** A classic example of aversion therapy (pharmacological) used in alcohol dependence by causing a toxic reaction (DER). * **Covert Sensitization:** A variation of aversion therapy where the noxious stimulus is merely **imagined** rather than physically applied. * **Systematic Desensitization:** The opposite of flooding; it involves graded exposure combined with relaxation techniques (based on reciprocal inhibition).
